i've had it adjusted three times now with new pads,fitting kits,disks and back plates it just does'nt seem to hold the car on a bit of a slope cant pull it up any futher no that it comes up to high now like when it was first done. What do you think?

So its time to get the job done properly then!

Never seen a garage set a handbrake up correctly yet (on almost any car!)

I think they tried to do it by adjusting at the disks only.  

As I understand it (correct me if I'm wrong anyone)
- the disk adjusters are to set the shoes just clear of the drums when the cable is slack
- the central adjuster then takes up the slack so that the handbrake activates at an appropriate number of clicks (4-5 is good I reckon).

So if you don't do the second step, even if the first is correct, you may not end up with the brake holding, even on maximum clicks - beacuse there is too much slack in the cable.

You should also free off the central adjuster/ensure the cable is slack before starting on the disk adjusters.

Its all in the guide.   Its a pain getting underneath but its the only way to do the job properly.

Yes this is the only way to do it!  Just ensure you soak the heat shield nuts in WD40 a bit before you do the job.

No, soak them ina  penetrating fluid, not an over rated glue remover.

Yes, Ian is correct.

Its key that the cable is VERY slack before doing any setup on the shoe position.

Its also key to trip the setup down and check the pivots etc on the actuator arm as they can sieze if not used (note to all auto drivers!)

.... as they can sieze if not used (note to all auto drivers!)

       it does get used .... when the tyre bay fitter puts in on and when the MOT tester tests it! ....... and the odd steep hill!!

Well WD40 has always worked brilliantly for me over the last 40 years Mark!

Clearly not somebody who has needed good additional lubrication then!

It is a truely poor lube and its penetration properties are only ona  par with light oil plus a dash of parafin

Have had 1990 carlton
1994 Corsa
Wife has got 2001 Astra
Did have 2002 Corsa, now daughters.
Got 2006 Astra.

Vauxhall handbrake - not the best.

Remember, 18 months or so ago an article in a magazine, read at the dentist that Vectra handbrakes aren't good.

Maybe a vauxhall fault???

Typical bull shite.....as already said, when serviced and adjusted correctly they are excellent.

What most people fail to realise is that when the handbrake is applied it is generally onto a hot disc / drum, as this then cools it will obviously contract thereby the shoes will not be exerting so much pressure.

The Vectra B issue was blamed on 'an insufficient hanbrake cable diameter' officially, but then how many of us pull the handbrake on that extra notch on a slope just to be sure which then stretches the cable no matter what it's diameter.

True if the handbrake is based on a disk caliper clamping a disk (as may be the case on a Vectra) but in the Omega's case the reverse is true. The drum contracts resulting in a greater force against the friction material.

I noticed on the Insignia test day that the majority of the models now have 'electronic' handbrakes, would this compensate for the contraction etc? Specifically would it compensate after the ignition had been turned off for a period of time???  :-/

Not on the Miggy ... "normal" brakes are the discs .. hand brake is the drum .. so unless you have been driving with the handbrake on (or doing J-turns ?? ) the handbrake drum is cold, and should never get hot as it should always be stationary whilst applied ...
